• added ixus90_sd790 1.00d BETA support, based on the work of: brake, sharky, snc, ehmu; provided by ehmu here: ​http://chdk.setepontos.com/index.php/topic,2187.msg44933.html#msg44933

Notes:

video may be buggy
fast shutter speed overrides (< 1/1500s) doesn't work
colormap probably needs adaptation

• added ixus960_sd950-100c to the makefile (copy of the 100d version, 100c and 100d are identical)
